Notes for 25 mg/mL
- At 25 mg/mL, 1 unit is 0.25 mg and 10 units is 2.5 mg.
- Listed doses up to 12.5 mg fit a 0.5 mL (50-unit) syringe.
- Listed doses up to 7.5 mg fit a 0.3 mL (30-unit) syringe.
Check the strength on every new vial
Units only mean something for one strength. If 50 units was 5 mg on a 10 mg/mL vial, the same 50 units from a 25 mg/mL vial is 12.5 mg, not 5 mg.
In July 2024 the FDA warned about dosing errors with compounded semaglutide, including mix-ups between mg, mL and units (FDA alert). The same math applies to any vial.
